Sine wave Applet

This applet maniputlates two sine waves and their sum.
The individual sine waves are red and blue, the sum is purple.
The "Sum" checkbox turns the display of the sum wave on and off.
Each individual sine wave has four controls --

a checkbox to turn the display of the wave on and off

a frequency box (the frequency must be between 20 and 1000 Hz)

an amplitude box (the amplitude must be between 0 and 100 %)

a phase box (the phase must be between 0 and 360 degrees)

To change a value, type in new value and press Return.
You must press Return each time you change a parameter.
If the screen does not update properly (primarily a
problem with Netscape 3.0), press "Images" to refresh the display.
